Questionnaire Design
A questionnaire is a formalized set of questions for obtaining information from respondents.
A questionnaire is sometimes called a Schedule, interview form or measuring instrument is a formalized set of questions for obtaining information from respondents
It is a part of data collection package that might also include a. Field Work Procedures b. Some Reward or Gift or Payment offered to respondents c. Communication aids, such as maps, pictures,
advertisements, products and return envelops
Questionnaire Definition
It must translate the information needed into a set of specific questions that the respondents can and will answer.
A questionnaire must uplift, motivate, and encourage the respondent to become involved in the interview, to cooperate, and to complete the interview.
A questionnaire should minimize response error.
Questionnaire Objectives
Lack of Theory
There are no scientific principles that guarantee an optimal or ideal questionnaire
Questionnaire Design is a skill
Questionnaire Design Process
Youth Research AchievesQuestionnaire Objectives
Youth research (YR) of Brookfield, Connecticut, conducts an omnibus survey
of children every quarter. Typically, YR interviews 150 boys and girls between
ages 6 and 8, along with 150 boys and girls between ages 9 and 12. YR uses
mall intercepts of mothers to recruit for its one-on-one interviews, which last
eight minutes. The study obtains children’s views on favorite snack foods,
television shows, commercials, radio, magazines, buzzwords, and movies.
Youth Research AchievesQuestionnaire Objectives
YR intentionally keeps its questionnaire to eight minutes because of attention span
limits of children. YR President Karen Forcade notes that some clients attempt to meet
all their research objectives with one study, instead of surveying, fine-tuning
objectives, and re-surveying. In doing so, these clients overlook attention limits of
young respondents when developing questionnaires.
“The questionnaires keep going through the
approval process and people keep adding
questions, ‘Well let’s ask this question, let’s add
that question, and why don’t we talk about this
also,’” Forcade said. “And so you end up keeping
children 25 minutes in a central location study and
they get kind of itchy.” The response error
increases and the quality of data suffers.
Forcade notes other lessons from interviewing children. When asking questions,
interviewers should define the context to which the question refers. “It involves
getting them to focus on things, putting them in a situation so that they can identify
with it,” Forcade said. “For example, when asking about their radio listening habits,
we said, ‘What about when you’re in Mom’s car, do you listen to the radio?’ rather
than, ‘How often do you listen to the radio? More than once a day, once a day,
more than once a week?’ Those are kind of big questions for little children.”
Questionnaires designed by
Youth Research to obtain
children’s views on favorite
snack foods, television shows,
commercials, radio,
magazines, buzzwords, and
movies attempt to minimize
response error.

Questionnaire Design Process
This is also the first step in design process
As the research project progresses, the information needed becomes more and more clear
The characteristics of the respondent group have a great influence on questionnaire design. Housewives and Students
1. Specify the Information Needed
In personal interview respondents see the interviewer thus lengthy, complex and varied questions can be asked
In telephone interviews the respondent does not see the interviewer and other constraints are there so short and simple questions
Questionnaires designed for Telephone and Personal Interviews should have conversational style
In Mail the questions are to be simple with detailed instructions
Email questionnaires have to be simple
2. Specify the Type of Interview Method
Department Store ProjectMail Questionnaire Please rank order the following department stores in order of your
preference to shop at these stores. Begin by picking out the one store that you like most and assign it a number 1. Then find the second most preferred department store and assign it a number 2. Continue this procedure until you have ranked all the stores in order of preference. The least preferred store should be assigned a rank of 10. No two stores should receive the same rank number.
Store Rank Order 1.Lord & Taylor ____________2.Macy's ____________..10. Wal-Mart ____________
Effect of Interviewing Method on Questionnaire Design
Telephone Questionnaire I will read to you the names of some department stores. Please rate
them in terms of your preference to shop at these stores. Use a ten point scale, where 1 denotes not so preferred and 10 denotes greatly preferred. Numbers between 1 and 10 reflect intermediate degrees of preference. Again, please remember that the higher the number, the greater the degree of preference. Now, please tell me your preference to shop at .......(READ ONE STORE AT A TIME)

Effect of Interviewing Method on Questionnaire Design
Personal Questionnaire (HAND DEPARTMENT STORE CARDS TO THE RESPONDENT). Here is a set
of department store names, each written on a separate card. Please examine these cards carefully. (GIVE RESPONDENT TIME). Now, please examine these cards again and pull out that card which has the name of the store you like the most, i.e., your most preferred store for shopping. (RECORD THE STORE NAME AND KEEP THIS CARD WITH YOU). Now, please examine the remaining nine cards. Of these remaining nine stores, what is your most preferred store for shopping? (REPEAT THIS PROCEDURE SEQUENTIALLY UNTIL THE RESPONDENT HAS ONLY ONE CARD LEFT)
Store Rank Name of the Store

Effect of Interviewing Method on Questionnaire Design
Electronic Questionnaire This question for e-mail and Internet
questionnaires will be very similar to that for the mail questionnaire.
In all these methods, the questionnaire is self-administered by the respondent.
Effect of Interviewing Method on Questionnaire Design
In personal interview respondents see the interviewer thus lengthy, complex and varied questions can be asked
In telephone interviews the respondent does not see the interviewer and other constraints are there so short and simple questions
Questionnaires designed for Telephone and Personal Interviews should have conversational style
In Mail the questions are to be simple with detailed instructions
Email questionnaires have to be simple
2. Specify the Type of Interview Method
If there is no satisfactory use for the data resulting from a question, that question should be eliminated.
It is useful to ask some neutral questions at the beginning of the questionnaire to establish involvement and rapport
Neutral questions are also asked when the topic of the questionnaire is sensitive or controversial
3. Individual Question ContentIs the Question Necessary?
Sometimes, several questions are needed to obtain the required information in an unambiguous manner. Consider the question,
“Do you think Coca-Cola is a tasty and refreshing softdrink?” (Incorrect)
Such a question is called a double-barreled question, because two or more questions are combined into one. To obtain the required information, two distinct questions should be asked:
“Do you think Coca-Cola is a tasty soft drink?” and “Do you think Coca-Cola is a refreshing soft drink?”
(Correct)
Individual Question ContentAre Several Questions Needed Instead of One?
In situations where not all respondents are likely to be informed about the topic of interest, filter questions that measure familiarity and past experience should be asked before questions about the topics themselves.
A “don't know” option appears to reduce uninformed responses without reducing the response rate.
3. Overcoming Inability To AnswerIs the Respondent Informed?
How many gallons of soft drinks did youconsume during the last four weeks? (Incorrect)
How often do you consume soft drinks in a typical week? (Correct)1. ___ Less than once a week2. ___ 1 to 3 times per week3. ___ 4 to 6 times per week4. ___ 7 or more times per week
Overcoming Inability To AnswerCan the Respondent Remember?
The inability to remember leads to errors of omission, telescoping and creation
Omission the inability to recall an event that actually took place
Telescoping refers to occurring more recently than it actually occurred
Creation error takes place when a respondent “remembers” an event that did not actually occur
Respondents may be unable to articulate certain types of responses, e.g., describe the atmosphere of a department store.
Respondents should be given aids, such as pictures, maps, and descriptions to help them articulate their responses.
Overcoming Inability To AnswerCan the Respondent Articulate?
Most respondents are unwilling to devote a lot of effort to provide information.
Hence the researcher should minimize the effort required from the respondents through questionnaires
Overcoming Unwillingness To AnswerEffort Required of the Respondents
Please list all the departments from which you purchased merchandise on your most recent shopping trip to a department store. In the list that follows, please check all the departments from which you purchased merchandise on your most recent shopping trip to a department store.
1. Women's dresses ____2. Men's apparel ____3. Children's apparel ____4. Cosmetics ____...16. Jewelry ____17. Other (please specify) ____
Overcoming Unwillingness To Answer
Context Respondents are unwilling to respond to questions which they consider
to be inappropriate for the given context. The researcher should manipulate the context so that the request for
information seems appropriate. Legitimate Purpose Explaining why the data are needed can make the request for the
information seem legitimate and increase the respondents' willingness to answer.
Ex – The consumption of cereals among different ages Sensitive Information Respondents are unwilling to disclose, at least accurately, sensitive
information because this may cause embarrassment or threaten the respondent's prestige or self-image.
Money, Family Life, Political, Religious Beliefs, Involvement in Accidents or Crimes
Overcoming Unwillingness To Answer
Place sensitive topics at the end of the questionnaire. Preface the question with a statement that the behavior of
interest is common. Ask the question using the third-person technique: phrase the
question as if it referred to other people.
Hide the question in a group of other questions which respondents are willing to answer. The entire list of questions can then be asked quickly.
Provide response categories rather than asking for specific figures.
Use randomized techniques.
Overcoming Unwillingness To AnswerIncreasing the Willingness of Respondents
Unstructured questions are open-ended questions that respondents answer in their own words.
1. Do you intend to buy a new car within the next six months?
__________________________________ 2. What is your occupation?__________________________________
3. Who is your favorite Professor?__________________________________
Choosing Question StructureUnstructured Questions
They enable the respondents to express general attitudes and opinions
Unstructured questions have less biasing influence
Respondents are free to express any views
Their comments and explanations can provide the researcher with rich insights and wide range of responses
A principle disadvantage is that potential for interviewer bias is high
Coding responses is costly and time consuming
Unstructured questionnaires are not suitable for Computer aided and self administered questionnaires (CAPI, CATI, Mail etc)
Disadvantages of Open Ended or Unstructured
1. What is your opinion about Levis Jeans?

Structured questions specify the set of response alternatives and the response format. A structured question may be multiple-choice, dichotomous, or a scale.
Choosing Question StructureStructured Questions
In multiple-choice questions, the researcher provides a choice of answers and respondents are asked to select one or more of the alternatives given.
Do you intend to buy a new car within the next six months?____ Definitely will not buy____ Probably will not buy____ Undecided____ Probably will buy____ Definitely will buy____ Other (please specify)
Choosing Question StructureMultiple-Choice Questions
A dichotomous question has only two response alternatives: yes or no, agree or disagree, and so on.
Often, the two alternatives of interest are supplemented by a neutral alternative, such as “no opinion,” “don't know,” “both,” or “none.”
Do you intend to buy a new car within the next six months?
_____ Yes_____ No_____ Don't know
Choosing Question StructureDichotomous Questions
Do you intend to buy a new car within the next six months?
Definitely Probably Undecided ProbablyDefinitely
will not buy will not buy will buywill buy

Choosing Question StructureScales
Define the issue in terms of who, what, when, where, why, and way (the six Ws). Who, what, when, and where are particularly important.
Which brand of shampoo do you use?(Incorrect)
Which brand or brands of shampoo have youpersonally used at home during the last month? In case of more than one brand, pleaselist all the brands that apply. (Correct)
Choosing Question WordingDefine the Issue
Choosing Question Wording
The W's Defining the Question
Who The RespondentIt is not clear whether this question relates to the individual respondent or the respondent's total household.
What The Brand of ShampooIt is unclear how the respondent is to answer this question if more than one brand is used.
When UnclearThe time frame is not specified in this question. The respondent could interpret it as meaning the shampoo used this morning, this week, or over the past year.
Where At home, at the gym, on the road?
“Do you think the distribution of soft drinks is
adequate?” (Incorrect)
“Do you think soft drinks are readily available when you want to buy them?”(Correct)
Choosing Question WordingUse Ordinary Words
In a typical month, how often do you shop in department stores?_____ Never_____ Occasionally_____ Sometimes_____ Often_____ Regularly (Incorrect)
In a typical month, how often do you shop in department stores?_____ Less than once_____ 1 or 2 times_____ 3 or 4 times_____ More than 4 times (Correct)
Choosing Question WordingUse Unambiguous Words
A leading question is one that clues the respondent to what the answer should be, as in the following:
Do you think that patriotic Americans should buy imported automobiles when that would put American labor out of work?
_____ Yes_____ No_____ Don't know
(Incorrect)
Do you think that Americans should buy imported automobiles?
_____ Yes_____ No_____ Don't know
(Correct)
Choosing Question WordingAvoid Leading or Biasing Questions
An alternative that is not explicitly expressed in the options is an implicit alternative.
1. Do you like to fly when traveling short distances? (Incorrect)
2. Do you like to fly when traveling short distances, or would you rather drive?
(Correct)
Choosing Question WordingAvoid Implicit Alternatives
Questions should not be worded so that the answer is dependent upon implicit assumptions about what will happen as a consequence.
1. Are you in favor of a balanced budget?
(Incorrect)
2. Are you in favor of a balanced budget if it would result in an increase in the personal income tax?(Correct)
Choosing Question WordingAvoid Implicit Assumptions
“What is the annual per capita expenditure on groceries in your household?” (Incorrect)
“What is the monthly (or weekly) expenditure on groceries in your household?”
and
“How many members are there in your household?” (Correct)
Choosing Question WordingAvoid Generalizations and Estimates
Questions that are in the form of statements should be worded both positively and negatively.
Choosing Question WordingDual Statements: Positive and Negative
Opening Questions The opening questions should be interesting,
simple, and non-threatening. Type of Information As a general guideline, basic information should be
obtained first, followed by classification, and, finally, identification information.
Difficult Questions Difficult questions or questions which are sensitive,
embarrassing, complex, or dull, should be placed late in the sequence.
Determining the Order of Questions
Effect on Subsequent Questions General questions should precede the specific
questions (funnel approach).
Q1: “What considerations are important to you in selecting a department store?”
Q2: “In selecting a department store, how important is convenience of location?”
(Correct)
Determining the Order of Questions
Logical OrderThe following guidelines should be followed for branching questions:
The question being branched (the one to which the respondent is being directed) should be placed as close as possible to the question causing the branching.
The branching questions should be ordered so that the respondents cannot anticipate what additional information will be required.

Flow Chart for Questionnaire Design
Divide a questionnaire into several parts. The questions in each part should be numbered,
particularly when branching questions are used. The questionnaires should preferably be
precoded. The questionnaires themselves should be
numbered serially.

2 hours to 2 hours 59 minutes...........-5
3 hours or more.................................-6
Less than 30 minutes.....................-1

(Please ignore the numbers alongside the answers. They are only to help us
in data processing.)
1. Considering all the times you pick it up, about how much time, in total, do
you spend reading or looking through a typical issue of THE AMERICAN
LAWYER?
Example of a Precoded Questionnaire
The questionnaire should be reproduced on good-quality paper and have a professional appearance.
Questionnaires should take the form of a booklet rather than a number of sheets of paper clipped or stapled together.
Each question should be reproduced on a single page (or double-page spread).
Vertical response columns should be used for individual questions.
Grids are useful when there are a number of related questions which use the same set of response categories.
The tendency to crowd questions together to make the questionnaire look shorter should be avoided.
Directions or instructions for individual questions should be placed as close to the questions as possible.
Reproduction of the Questionnaire
Pretesting refers to the testing of the questionnaire on a small sample of respondents to identify and eliminate potential problems.
A questionnaire should not be used in the field survey without adequate pretesting.
All aspects of the questionnaire should be tested, including question content, wording, sequence, form and layout, question difficulty, and instructions.
The respondents for the pretest and for the actual survey should be drawn from the same population.
Pretests are best done by personal interviews, even if the actual survey is to be conducted by mail, telephone, or electronic means, because interviewers can observe respondents' reactions and attitudes.
